"WINDING AND HAUDAGE DRUM.

Specification of Letters Patent.

Patented Sept. 1-5, 1914.-

Application filed November 29, 1913. Serial in. 808,868.

To all whom it may concern Be it known that I, CARL DAvENPon'r, a subject of the King of Great Britain and llreland, residing at the Aztec Works, Neepsend, Sheliield, in the county of York, England, have invented new and useful Improvements in Winding and Haulage Drums, I

of which the following is a specification.

This invention relates to winding and haulage drums and in particular to a haulage drum of es ecial value for use in collieries and enera ly in connection with mines. According to my invention I produce a haulage drum which entirely houses the engine or motor, the'requisite gearing, and other moving parts, leaving only control mechanism exterior to the drum. I thus accommodate the engine and gearing in a closed casing which afiords perfect protection to engine and gear and prevents access of all dirt and dust. Further, this method of locating engine and gear enables me to keep the haulage plant extremely comthe. up er half in sectii'm.-

pact, thus economizing space in the mine; to use a system of splash lubrication; and to producea haulage drum which can be run with an absolute minimum of risk as regards accidents An additional point is, that with the engine and gearing located within the'drum, no tampering by an an authorized person can occur.

The construction of the new haulage drum will be clearly understood from the following detailed description having regard to the attached drawings, in which Figure 1 represents a longitudinal sectional elevation of my new haulae drum or windin apparatus. Fig. 1 is a etail view. Fig. 2 s ows an end elevation of Fig. i with hi. 3 is a broken ongitudinal detail sections view and shows the passages in the fixed crankshaft and the ports leading to and from thecylinders. Fig. 4 is a cross sectionof Fig. 3 taken on the line X--X. Fig. 5 shows-a detail section of a modification in the fluid distributing sleeve arrangement which may be used in connection with the fixed crank shaft, and Fig. 6 is a longitudinal section of this modified arrangement.

I make use of a windin drum in the form of a turned'hollow casting'of suitable dimensions and such as is marked 1 in the drawings, and I locate 'or place therein the motor or engine of whatever type, so that, the motor. or engmeis entirely accommodated within the interior of the drum 1. I prefer to employ a multi-cylindered engine and I show an engine having three cylinders marked 2. Such an engine is intended to be actuated by compressed air, but steam or other fluid pressure may be u ed. The cylinder's 2 are arranged to revolve around a crank 7 pin 3 forming part of a fixed two armed crank shaft 4. Such fixed shaft 4 is supported by two end bearings 5, 5, from frame- Work such as the steel girders 7, 8, and such shaft is of sufiicient strength to sustain the rotatable cylinders 2, 2, 2, which are carried upon disks 9, 10. These disks 9 and 10 along with the cylinders 2, 2, 2, revolve around the fixed crank shaft t due to the power developed in the open ended cylinders 2, 2, 2. The connecting rods 11 of the pis tons in said cylinders all converge on the crank pin 3 of the fixed crank shaft. The lefthand end of the crank shaft is formed with passages which maybe styled inlet and exhaust passages 12 and 13 which communicate (via the chest it) necessarily with the channels 15, 16, 17 leading to the cylinders and such channels 15, 16, 17 lead both to and from each cylinder but occur only in the revoluble disk 9. "Upon the boss of the disk 10 l[ secure a spur pinion 18 and this ears into a spur wheel 19 fixed on a rave uble shaft 22 supported by ball hearings at 21 in an extension from the fixed sleeve 22 which carries the right-hand half of the fixed crank shaft 4. The removable right-hand check of the drum 1 revolves normally aroundthis fixed sleeve, as Fig. 1 clearly shows. Upon the short shaft 20 is fixed a spur pinion 23 and this gears with a larger internal spur pinion 24lfixed'on the drum chwk. Thus, rotatory motion from the two disks 9, 10 can be communicated through the spur gear to the drum and the drum is thereby rotated. Upon the right-hand extremity of the sleeve surrounding the fixed crank shaft 4 I key a clutch pulley 25 which is encircled by a'llexible band. 26 one end of which is anchoredwhile the other carries an ear 27. A screwed shaft 28' carried in extensions from the end bearing 5 engages such car 27 and such shaft 28 has an actuating hand wheel 29. By such means the flexible. band 26 can be contracted around the pulley 25. When this, is done, rotation disposed as to press against a tapered bush 34 fitted inside the boss of the disk 9 on the port side. This tapered bush 34 is thus thus permitting the gear' to be carried around andthe drum is released. This ar-' rangement provides a free-wheel device obv tainable at will,

From the foregoing it is clear that with the flexible band 26 contracted, the engine with its disks 9, 10 revolves around the fixed crank shaft 4, and motion is transmitted through the spur wheels 18, 19, 23 and 24 to the drum 1. The drum 1 is provided with suitable flanges for the rope or cable. The

diameters of the-spur wheels are preferably so proportioned that the drum makes a less numberof revolutions than the rotating cylinders &c.

I carry the left-handcheek of the drum 1 conveniently upon a sleeve .30 the inner end of which-sleeve is bored to form a recess or chamber 31 into which is fitted a spring 32 which occurs.

which acts on a washer 33 (see Fig. 3) so under the-influence of. the spring 32 and is prevented from. independent rotation by a feather key 35. This tapered bush is self adjusting and automatically takes up any wear Such bush'34 is drilledto provide inlet and exhaust passage ways-at three points 15", 16*, and 17", for ingress-and egress of fluid pressure,5 'see the Figs. 3 and 4. 1

The hollow or port end of the fixed crank shaft 4 is cut with two passage ways 12 and 13 either of which may serve for inlet or exhaust, and, the fluid pressure is controlled by a simple Di slide valve 36"fitted'in the valve chest 37; the 'valve 36 is shown as worked by rack and pinion gear 38 controlled by the handle 39. A dial 40 is fitted, over which a pointer 41 fitted on the shaft .42 works. Su posing, for example, that passage-12 is or the time being the fluidpressure channel, then 13 is the exhaust channel. It is to be clearly understood,that, by reversing the slide valve, the drum 1 can be at once "reversed;'the passage 13 then-becomes the fiuid pressure channel-and 12-the exhaust channel. I may use a rotary valve in place ofthe D slide valve to control the, .fluid pressure. v

'As a modification in the manner of packing the rotatory disk with respect to the bored end of the fixed crank s aft I may employ the arrangement "shown by Figs. 5

to provide passage ways for the fluid to and from the revolving cylinders. This allows the bush 34 to'be'niade an easy fit and permits floating to a slight extent.

I provide a suitable brake for the drum, such as the brake strap 50 anchored as to one end at 51. and actuated by the foot-lever 52 fulcrumed at 53, the brake being normally held off by the spring 54.

Suitable rovision is made to introduce a supply of lubricant to the interior A .of the drum to constitute an oil bath, so that, when the drum is at work all the inferior mechanism is'lubricated by asplash system. Lubricant can be introduced by removing one of the air. boxes 56.

In order to allow any air pressure liber ated through the holes 55,, or leaking, to readily escapefrom the interior A. of the drum I fit one or more removable air boxes 56 each having abafile plate 57, which bafile plate while allowing the escape of air under pressure (through the holes 58) serves to a great extent to. prevent the passage of oil along with the air. Any or allof the may revolve on ball bearings.
